Title: Patterning method for laminated wiring
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/3213
Filed: 1994-10-12
Abstract: PURPOSE: To make it possible to carry out anisotropic etching without causing side etching or particle contamination for a laminated wiring made of an Al- based metallic layer on a tungsten layer with good anti-migration characteristics. CONSTITUTION: After an aluminum-based metallic layer 5 is etched with Br- based gas, a refractory-metal layer 4 is patterned with a mixed gas of Cl-based gas and an oxygen-based gas. A process for causing a passive state for a side face of a pattern in the aluminum-based metallic layer 5 may be carried out. The aluminum-based metallic layer 5 on the patterning side is covered with a strong side-face protective film 81 including Br element, and the side etching is prevented during the etching for the refractory-metal layer 4. In this way, an F-based gas is not used, so the side-face protective film 8a doesn't remain as a fence-shaped AlFx -based residual.

Title: Active matrix display and production thereof
Inventor: TANIGUCHI KOJI
IPC: G02F1/1368
Filed: 1989-09-20
Abstract: PURPOSE:To prevent the disconnection of the drain electrodes, etc., of TFT elements formed on a glass surface formed with black stripes by forming the substrate to have a flat surface having no steps. CONSTITUTION:A resist 2 having the reversal patterns of the black stripes 3 is formed on the glass substrate 1. The surface of the glass substrate 1 which is not coated with the resist 2 is then etched by using the buffer hydrofluoric acid of a hydrofluoric acid etchant and is thereby formed with etching grooves 25 having grating patterns. The depth of the grooves 25 is equaled to the layer thickness of the stripes 3. A Cr film is deposited by evaporation as a metallic film 26 to form the stripes 3 over the entire surface on the substrate 1. The resist 2 on the substrate 1 is dissolved by an org. solvent and the resist 2 and the metallic film 26 on the resist are removed. The remaining metallic film 26 is patterned to form the stripes 3. The stripes 3 are thereby embedded into the etching grooves 25 formed on the surface of the glass substrate 1, by which the flat surface of the substrate 1 having no steps is obtd. The disconnection of the picture element electrodes 9 and drain electrodes 10b is thus prevented.
